Title: Torque multiplier for bicycle - has increased pedal starting force using small orbital chain drive gearwheel
IPC: B62M9/00
Filed: 1991-07-23
Abstract: The starting force exerted on the pedals (N) and cranks (J) in the first stage with a double-cogged chain drive pinion (1) of the central axis (Z) with nineteen teeth per 8mm to produce and transfer the attraction force is guided by an endless double chain (7).This has 8mm divisions  over a double cogged chain gearwheel (2) with 8mm division per 18 teeth of the planetary gear wheel (3) over the double chain guide wheel (4) = 16 teeth 8mm division back to the starting point (a).

Patent DE-4132024-A1 (DE)
Title: Vehicle floor tufted carpeting for effective wear - has increased pile yarns at areas subject to mechanical wear and fewer yarns in decorative zones, for material redn.
Inventor: HIRT WOLFGANG
IPC: D05C17/02
Filed: 1991-09-26
Abstract: An increased amt. of pile yarns are inserted into the ground material in the zones where greater mechanical wear is anticipated than in the other sections. The pref. amt. of pile yarn to be used is controlled by the gap between burls inserted laterally and/or longitudinally and/or through the burl height. The pile yarns vol. is increased in the carpeting where it is trodden and reduced in areas which are decorative. No pile yarn is used in carpet sections which are invisible. At the decorative and invisible zones, the burls are so low that they are not cut by the tufting machine blade. A weaker pile yarn is used in the decorative or invisible areas. Pile yarns of different quality are fed to the tufting machine needles. The ground material is fed through the tufting machine, in steps, at different speeds. Those areas of the carpeting which are only used to centre and align the material, and later trimmed off, are not tufted. The tufting machine needles are controlled separately. ADVANTAGE - Requires less material, by structuring the use of material at carpet areas subject to the greatest wear.

Title: Quantitative determination of degree of hardening of lacquer layers pref. on optical fibres - by solvent extracting layer then chromatographically separating unreacted monomer and determining monomer content by UV spectroscopy
Inventor: HOFFART MICHAEL DIPL ING
IPC: G02B6/44
Filed: 1992-09-29
Abstract: In the ascertaining of the deg of hardening of a monomer-contg. UV-hardened lacquer coating the remaining monomer content is determined by extracting the hardened layer using a solvent. Monomer is separated from the extract by liq chromatography then determined by UV spectroscopy. The deg of hardening of the coating is also determined. Pref., the coating may consist of several separate layers, prep. from different monomers, and the monomer components for the various layers are separated, the monomer contents ascertained and the hardening degrees of the layers determined. The solvent is pref. acetonitrile and extraction is carried out at low temp. The process can be used for calibration of the lacquers. by using extraction processes of different lengths the monomer contents of multiple layers or of differing depth of layer may be ascertained. USE/ADVANTAGE - For the protective layers on quartz glass fibres used in optical communications technology. The method is more specific than prior art processes, as only the monomer content of the extract is considered.

Filed: 1992-11-17
Abstract: A detection method for methicillin-resistant Staphylococcus aureas (MRSA) or parts thereof in a sample using the disclosed peptides or derivs. thereof in immunological reactions with samples contg. antibodies against the MRSA and detection of an immunological complex. Also calimed is (a) MRSA-antibody detection in a sample using the disclosed and immobilised peptides, (b) isolated substantially pure MRSA-Penicillin binding protein (PBP) 2'-antigen, purified by affinity chromatography using a gel coupled to at least one of the peptides shown, (c) peptides of the sequences shown, (d) polyclonal and monoclonal antibodies reacting with MRSA-PBP2', (e) antibodies produced by hybridomas DM2-12, DM2-13, DM2-39, DM2-40, DM2-45, DM4-11, DM4-17, DM4-20, DM4-26, DM4-32, DM3-1. DM3-19 and DM3-26. USE/ADVANTAGE - Staphylococcus aureus causes dermatitis, pneumonia and organ failure. Since MRSA-infections are resistant to antibiotics and antimicrobial medicaments, for proper medication it first has to be established whether the disease is caused by MRSA, i.e. using the method above. Additionally MRSA is highly infectious and its detection is vital for appropriate precautions. In contrast to prior art methods using SDS-polyacrylamide gel electrophoresis for PBP2' in which the protein is often not pure and denatured thereby inhibiting the detection after cumbersome processing, the synthetically produced peptides in this method provide a simple and accurate MRSA-testa'-

Title: Method for the demand-controlled program-loading of decentralised processor devices in a digital communication system
Inventor: GERICKE HARALD
IPC: H04Q3/545
Filed: 1993-03-31
Abstract: Starting with a communication system having a central processor device DP and a number of decentralised processor devices BG, into which programs are transmitted from the central processor device DP during a cold start (or hot start), it is proposed that the decentralised processor devices BG, after activation of a reset signal (PRS) relating to them, first read the storage area provided for storage of the control program in their respective local memory and form a signature information. This signature information is compared with a preset signature information stored at the time of a preceding program-loading and it is only when they are not identical, that a load-call message is transmitted to the central processor device DP. This method increases the availability of the communication system since redundant loading, for example after a programmed reset, is avoided. <IMAGE>

Title: Washing machine having a lower weight and a clearly reduced water consumption due to a return of rinsing water
Inventor: AUSTEL HARALD DIPL ING
IPC: D06F37/20
Filed: 1993-07-10
Abstract: The invention relates to a washing machine, particularly for domestic use, which works with a clearly reduced water consumption as a result of a return of the rinsing water. The water-collecting tank or tanks is or are designed so that vibrations which occur are damped substantially more effectively and the otherwise conventional compensating masses become superfluous. Because of the absence of compensating masses, the machine, which works clearly more cost-effectively during operation is also cheaper to transport and can be recycled in a simpler way.
